Ultrasound elastography adds no additional value to combined B-mode and color Doppler sonography for differentiation of benign and malignant cervical lymph nodes.

AIM: To evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings of cranial intraosseous meningiomas (IOMs). MATERIAL and METHODS: This study included ten patients (six females and four males) with IOMs who underwent cranial CT and/ or MRI examinations during May 2009-June 2018. Lesions were classified based on the following locations: the sphenoid ridge, the calvarial convexity, other skull base bones, and the sphenoid ridge + calvarial extension. Bony extension, contour irregularity or radial bone spiculation, bony changes (hyperostotic, lytic, or mixed patterns), dural calcification, cerebral edema, and the presence of soft tissue were evaluated. RESULTS: A total of eleven IOMs were identified in ten patients. The age of patients was 46-80 (mean: 55.30 ± 9.84) years. Five of the lesions were located in the sphenoid ridge + calvarium, three in the sphenoid ridge, two in the skull base, and one in the calvarial convexity. Seven lesions exhibited radial bone spiculation. Moreover, nine lesions exhibited hyperostotic CT pattern; while, two exhibited a mixed pattern. Three IOMs were accompanied with dural calcification, and peritumoral edema was observed in six IOMs. CONCLUSION: IOMs are predominantly low-grade tumors, commonly located in the periorbital area and often accompanied by soft tissue components and dural infiltrations. They most commonly lead to radial bone spiculation and bone expansion. Patients primarily have single lesions but may occasionally have multiple ones.

Hydatid disease is an endemic zoonosis, and patients are generally from cattle- and sheep-raising regions of the world, such as Central Europe, the Mediterranean, the Middle East, China, South America, Australia, New Zealand, South Africa, and Russia (Lewall and McCorkell in Radiology 155:773-775, 1985). Furthermore, hydatid cyst is a disease of immigrants in non-endemic countries and in developed countries (Stojkovic et al. in PLoS Negl Trop Dis 6:e1880, 2012). The most common affected organs are liver and lungs. Hydatid cyst located in the subcutaneous tissue constitutes an extremely rare manifestation of the hydatid disease (Săvulescu et al. in Chir Buchar Rom 1990 105:419-422, 2010). In this study, we report an uncommon case of hydatid cyst that developed in the subcutaneous tissue of the right thigh of a patient with ultrasound, computed tomography, and magnetic resonance imaging findings.
